I am a fellow Bruxer and was wearing my right side teeth flat. I have been wearing a specially molded hard occlusal night guard which I got from the dentist for over 4 years. Back then it cost me about $300 which was ALOT for me, but I am so grateful now that I made the investment. I find that I grind every night. The grinding is just worse when I am stressed or when I have one of my frequent sinus infections. I have such force in my grinding that I actually put a crack in my first guard within the first 6 months. Luckly it was still under warranty and I got another one. That is the guard I am still using 3 1/2 years later. I have some definite worn spots on it which make me appreciate it even more because that wearing would have been on my teeth. The guard took a bit of getting used to, but now I miss it if I don't have it in at night. I had a large tori (boney ridge that I formed as a result of the grinding) removed from my outer jaw last week and I haven't been able to wear the guard yet. The doc said it would be a while before I could. Anyway, I am so used to the guard that I have been waking up with my tongue between my teeth trying to take it's place. Unfortunately, I have been bruising my tongue. I never thought I would say this, but I am looking forward to the day I can wear the guard again.
I know this was long. I hope it helps.
